  Dmitry Mendeleyev - MSN Encarta
Dmitry Ivanovich Mendeleyev was born in Tobol’sk, Siberia.
Mendeleyev was a renowned teacher, and, because no good textbook in chemistry was available, he wrote the two-volume Principles of Chemistry (1868-1870), which became a classic.
Mendeleyev's investigations also included the study of the chemical theory of solution, the thermal expansion of liquids, and the nature of petroleum.

In 1860, Mendeleyev discovered the concept of critical temperature (see critical constants) and attended the first International Chemical Congress at Karlsruhe, where Stanislao Cannizzaro's views on atomic weights planted the seeds for the concept of the periodic table.
Mendeleyev served as professor of chemistry at the Saint Petersburg Technological Institute (1864-66) and at the University of Saint Petersburg (1867-90), a post that he resigned in protest against the administration's treatment of student petitions for reform.
Mendeleyev also worked on the liquefaction of gases; the expansion of liquids; a theory of solutions; a theory of the inorganic origin of petroleum; the chemistry of coal; Russian weights and measures; and the universal ether.

 PERIODIC LAW
The key to the success of their efforts was the realization that previous attempts had failed because a number of elements were as yet undiscovered and that vacant places must be left for such elements in the classification.
The discovery of scandium proved to be one of a series of dramatic verifications of the predictions based on the periodic law, and validation of the law accelerated the development of inorganic chemistry.
In the latter category is the group of elements known as the rare earth elements, which are so similar in properties that Mendeleyev had to assign all 14 to a single place in his table.

Mendeleyev was the first chemist to understand that all elements are related members of a single ordered system.
Mendeleyev was born in Tobol'sk, Siberia, and studied at St Petersburg and in Germany at Heidelberg.
Mendeleyev was convinced that the future held great possibilities for human flight, and in 1887 he made an ascent in a balloon to observe an eclipse of the Sun.

Mendeleyev's Dream has more detail on the earlier practice of alchemy and about the lives of the people in many of the stories in common.
Its penultimate chapter includes the stories of several twentieth-century scientists whose discoveries about the quantum mechanical atom explain the periodic properties of Mendeleyev's table, and it closes with a whirlwind tour of subatomic particles (among them protons, neutrons, mesons, electrons, and neutrinos) and sub-subatomic quarks and superstrings.

Mendeleyev was born in Tobol'sk, Siberia, on 7 February 1834, the youngest of the 17 children of the head of the local high school.
According to Mendeleyev the properties of the elements, as well as those of their compounds, are periodic functions of their atomic weights (relative atomic masses).
Far-sighted though Mendeleyev was, he had no notion that the periodic recurrences of similar properties in the list of elements reflect anything in the structures of their atoms.

Mendeleyev was born in 1834, and was the Russian chemist who developed the periodic classification of the elements.
Mendeleyev's formulation of the periodic law, which permitted the observation of the relationships among the elements that previously had been studied only in isolation.
Mendeleyev died in 1907, and saw his text book go through many editions, but without doubt, his most significant and lasting contribution was the creation of the periodic table.

Mendeleyev was the 17th and last child of the director of the gymnasium at Tobolsk.
It was Mendeleyev, however, who formulated the periodic law, according to which, when all known elements are arranged in order of increasing atomic weight, the resulting table shows a periodicity of properties and allows one to observe the many types of chemical relation hitherto studied only in isolation.
Mendeleyev's last years were saddened not only by declining health but by the political events that preceded the Russian Revolution of 1905.

Chemistry has been a neglected area of science writing and Mendeleyev, the king of chemistry, is a largely forgotten genius.
Just as Newton’s laws and Darwin’s theory of evolution laid the foundation for modern physics and biology respectively, it was Mendeleyev’s Periodic Table that provided the bedrock for chemistry.
For example, Mendeleyev’s Periodic Table was so successful because it was predictive as well as descriptive.

 The Case of Mendeleyev: LaRouche's Method and the Physical Sciences   (Site not responding. Last check: 2007-10-26)
Mendeleyev explains that he had discovered the existence of a periodic system of elements, but had not yet been able to formulate the law and table.
So Mendeleyev predicted that there must be, given the universality of the law, elements which will be discovered with the characteristics indicated by their place in the ordering expressed by the table.
And Mendeleyev used the Sanskrit word eka, which means ``the next one,'' and gave names to the undiscovered elements, in the first case eka aluminium and in the second case, eka silizium, or silicon.

Mendeleyev was "matched" at the age of 29 by an elder sister worried about his bachelordom.
Dimitri Mendeleyev believed that valence was the most significant property of an element, and decided to order the elements in columns of equal valence, with atomic weight increasing down the column.
Mendeleyev's success reminds one of the story of Einstein who, when confronted with the news that a certain astronomical observation agreed with a rival's prediction rather than his own, said "The observation is wrong; my theory is the more elegant and must be correct" - and he was right.

 CONTEXT - This Week in Arts and Ideas from The Moscow Times
The incongruous presence of this apartment in the midst of a modern university was due to the fame of its one-time tenant, Dmitry Mendeleyev, whose periodic table of elements remains a major contribution to chemistry.
Mendeleyev is presented as an ambitious conservative intent on integrating science into mainstream life and on fomenting reforms that would preserve the tsarist autocracy for future generations.
Some scientists overtly called him amateurish and superficial, while his stubborn commitment to the concept of the chemical ether, a supposed pillar of "the unity of the forces of nature," was typical of scientists who, once having made a great discovery, insist on its validity in the face of mounting empirical evidence to the contrary.

 Mendeleyev's Dream: The Quest for the Elements Book at Shop Ireland
Even though the title of this books suggests that it's about Mendeleyev and his famous dream, most of the book is taken up with the history of chemistry that led up to the moment when Mendeleyev dreamed his dream.
MENDELEYEV'S DREAM is the story of chemistry, from the ancient Greek, Anaximenes, with his theory of air as the fundamental element compressible to water and stone, to the gnomic Russian genius, Mendeleyev, who conceived the Periodic Table in the mid-19th century.
Although little time is spent on Mendeleyev himself (I would actually have liked to learn a little bit more about the man), this book beautifully traces the history of chemistry, from the ancient Greeks, over the alchemists, to early-twentiest century chemistry.

 Schiller Institute Vernadsky Paper by Lyndon LaRouche
The same must be argued as a conclusion implicit in Mendeleyev's notion of a process of generation of the existence of the Leibnizian monads of the periodic table.
The problematic, popular variety of classroom or textbook error to be avoided, is to be recognized as the presumption that material existence is originally of the form which naive sense-certainty expresses as an aprioristic form of geometry or algebra.
Mendeleyev's principle of generation expressed by the periodic table, and Vernadsky's experimental approach to the universality of the distinctions of life and cognition, are examples of a unique, or universal experiment: a principle proven experimentally to be a universally valid hypothesis.
